                        to lock a page (or record for the QUEUE access
                        method) and hold it to the end of a transactions.

                        Initialize lockers. Each thread which is active in a
                        transactional environment will use a locker structure
                        either for each transaction which is active, or for each
                        non-transactional cursor that is active.

                        which is opened for writing in a transactional environment,
                        a log fileid structure is used.

                        BDB library that it will no longer be making calls, unused
                        structures may accumulate until a cleanup is triggered either
                        using a high water mark or by running
